Description:
On-board diagnostics (OBD) is an automotive term referring to a vehicle's
self-diagnostic and reporting capability. OBD systems give the vehicle owner or
repair technician access to the status of the various vehicle sub-systems. The
amount of diagnostic information available via OBD has varied widely since its
introduction in the early 1980s versions of on-board vehicle computers.
Early versions of OBD would simply illuminate a malfunction indicator light or
"idiot light" if a problem was detected but would not provide any information as
to the nature of the problem. Modern OBD implementations use a standardized
digital communications port to provide real-time data in addition to a
standardized series of diagnostic trouble codes, or DTCs, which allow a person
to rapidly identify and remedy malfunctions within the vehicle.
OBD-II is an improvement over OBD-I in both capability and standardization. The
OBD-II standard specifies the type of diagnostic connector and its pinout, the
electrical signaling protocols available, and the messaging format.
It also provides a candidate list of vehicle parameters to monitor along with
how to encode the data for each. There is a pin in the connector that provides
power for the scan tool from the vehicle battery, which eliminates the need to
connect a scan tool to a power source separately. However, some technicians
might still connect the scan tool to an auxiliary power source to protect data
in the unusual event that a vehicle experiences a loss of electrical power due
to a malfunction. Finally, the OBD-II standard provides an extensible list of
DTCs.
As a result of this standardization, a single device can query the on-board
computer(s) in any vehicle. This OBD-II came in two models OBD-IIA and OBD-IIB.
OBD-II standardization was prompted by emissions requirements, and though only
emission-related codes and data are required to be transmitted through it, most
manufacturers have made the OBD-II Data Link Connector the only one in the
vehicle through which all systems are diagnosed and programmed.
